Abstract
Description
La présente invention concerne de manière générale les dispositifs d'éclairage.The present invention generally relates to lighting devices.
Elle concerne plus particulièrement un dispositif d'éclairage du type constitué d'un récipient à parois au moins partiellement transparentes ou translucides, ce récipient contenant un combustible thermofusible intégrant au moins une mèche, l'extrémité libre de cette mèche étant susceptible d'être enflammée pour éclairer.It relates more particularly to a lighting device of the type consisting of a container with at least partially transparent or translucent walls, this container containing a hot-melt fuel incorporating at least one wick, the free end of this wick being liable to be ignited to light up.
Les dispositifs d'éclairage du type précité sont bien connus à ceux versés dans cet art. Ils présentent l'avantage, par rapport à des dispositifs d'éclairage de type bougie classiques, d'éviter des coulures de la matière combustible lors de son chauffage. Par ailleurs, ils permettent d'obtenir de manière simple des dispositifs d'éclairage de forme variée. Toutefois, de tels dispositifs d'éclairage nécessitent l'utilisation d'une quantité de combustible importante.Lighting devices of the aforementioned type are well known to those skilled in the art. They have the advantage, compared to conventional candle-type lighting devices, to prevent sagging of the combustible material during its heating. Moreover, they make it possible to obtain, in a simple manner, lighting devices of various shapes. However, such lighting devices require the use of a large amount of fuel.
Le document US-A-4 894 008 divulgue un dispositif d'éclairage selon le préambule de la revendication 1.US-A-4,894,008 discloses a lighting device according to the preamble of claim 1.
Un but de la présente invention est de proposer un dispositif d'éclairage du type précité dont la conception permet de réduire fortement la quantité de combustible thermofusible nécessaire au fonctionnement du dispositif, et qui permet une plus grande securité.An object of the present invention is to propose a lighting device of the aforementioned type whose design greatly reduces the amount of hot melt fuel required for the operation of the device, and which allows greater security.
A cet effet, l'invention a pour objet un dispositif d'éclairage du type constitué d'un récipient à parois au moins partiellement transparentes ou translucides, ce récipient contenant un combustible thermofusible intégrant au moins une mèche, l'extrémité libre de cette mèche étant susceptible d'être enflammée pour éclairer, caractérisé en ce que le récipient est partiellement rempli d'un liquide non combustible enfermé dans le récipient par le combustible thermofusible formant bouchon.For this purpose, the subject of the invention is a lighting device of the type consisting of a container with at least partially transparent or translucent walls, this container containing a hot-melt fuel incorporating at least one wick, the free end of this wick. being capable of being ignited for illumination, characterized in that the container is partially filled with a non-combustible liquid enclosed in the container by the hot melt plug fuel.
Selon une forme de réalisation préférée de l'invention, le liquide non combustible est un liquide, de préférence aqueux, transparent ou translucide, coloré ou non.According to a preferred embodiment of the invention, the non-combustible liquid is a liquid, preferably aqueous, transparent or translucent, colored or not.
L'invention sera bien comprise à la lecture de la description suivante d'un exemple de réalisation, en référence à la figure unique qui représente une vue schématique en coupe d'un dispositif d'éclairage conforme à l'invention.The invention will be better understood on reading the following description of an exemplary embodiment, with reference to the single figure which shows a schematic sectional view of a lighting device according to the invention.
Comme le montre cette figure unique, le dispositif d'éclairage, objet de l'invention, est constitué d'un récipient 1 à parois au moins partiellement transparentes ou translucides pour permettre la visualisation du contenu du récipient. Ce récipient 1 peut affecter un grand nombre de formes. Dans l'exemple représenté, ce récipient 1 est constitué par un verre à pied. La matière constitutive de ce récipient peut être du verre, une matière plastique ou toute autre matière apte à supporter une élévation de température. Ce récipient 1 est partiellement rempli d'un liquide 4 non combustible. Ce liquide 4 non combustible est, dans l'exemple représenté, constitué par de l'eau. Toutefois, tout autre liquide généralement transparent ou translucide, coloré ou non, aurait pu être utilisé. Ce liquide 4 non combustible est maintenu à l'intérieur du récipient 1 par un combustible 2 thermofusible formant bouchon. Ce combustible 2 thermofusible peut être constitué d'un gel coulé à chaud à la surface du liquide 4 pour adhérer, après refroidissement, aux parois du récipient 1. Ce combustible 2 sera donc généralement un gel élastomère hydrophobe à base au moins d'huile de paraffine hydrogénée et de produits copolymères. Ce type de gel est bien connu à ceux versés dans cet art et est notamment commercialisé sous la dénomination CANDEL'GEL par la Société CANDELIS SARL. Bien évidemment, la densité du combustible 2 est inférieure à la densité du liquide 4. Ce combustible 2 peut encore contenir au moins une substance odoriférante et/ou un colorant pour accentuer le contraste entre combustible 2 et liquide 4 non combustible. Le récipient 1 peut enfin contenir un solide 5 pour réduire la quantité de liquide 4 à introduire dans le récipient 1. Ce solide 5 sera généralement constitué par un élément décoratif. Ce solide 5 est de préférence collé aux parois du récipient 1 de manière à maintenir un positionnement précis de ce solide 5 à l'intérieur du liquide 4.As shown in this single figure, the lighting device, object of the invention consists of a container 1 with walls at least partially transparent or translucent to allow viewing of the contents of the container. This container 1 can affect a large number of shapes. In the example shown, this container 1 is constituted by a stemmed glass. The constituent material of this container may be glass, a plastic material or any other material capable of withstanding a rise in temperature. This container 1 is partially filled with a
Lors de la fabrication d'un tel dispositif d'éclairage, on procède de la manière suivante. Le récipient 1 est rempli du liquide 4. A l'intérieur du volume de ce liquide 4, il est éventuellement introduit un solide 5 immobilisé ou non aux parois du récipient 1. Un combustible 2 thermofusible est chauffé à une température supérieure à sa température de fusion puis laissé à refroidir quelques instants avant coulage à la surface du liquide 4. A titre d'exemple, le combustible est chauffé à une température de fusion de l'ordre de 120°C puis refroidi à une température de 80°C. Cette étape de refroidissement permet d'éviter un bullage du combustible 2 à la surface du liquide 4. Ce combustible 2 est un gel coulé à chaud à la surface du liquide 4, de préférence sous forme d'au moins deux couches successives. La coulée de la seconde couche ne se fait qu'après refroidissement de la première couche. Avant coulée de la seconde couche, la mèche 3, généralement équipée, à son extrémité opposée à son extrémité libre 3A susceptible d'être enflammée, d'une platine, est disposée, par l'intermédiaire de cette platine, à la surface de la première couche. La seconde couche de combustible est coulée de sorte que la mèche 3 est intégrée dans la seconde couche. Le combustible utilisé formant ainsi bouchon du récipient est introduit dans une quantité telle qu'une extrémité de la mèche 3 fait saillie du bouchon et peut être ainsi enflammée pour permettre l'éclairage de l'ensemble. Un tel dispositif fonctionne alors à la manière d'une bougie par simple inflammation de l'extrémité libre de la mèche.During the manufacture of such a lighting device, the procedure is as follows. The container 1 is filled with the
